Application filed. April 5,

To all 107mm it may concern .i

Be it known that I, MITSU UNo, a citizen of Japan, residing at SanFrancisco, in the ject to provide a simple and inexpensive toolforengagement with the rail of the track and bywhich the application ofa relatively small amount of force will be capable of shifting" thetrack or rail laterally to straighten or align the same. A furtherobjectflof this invention is to provide a simple and inexpensive devicefor the purpose named and in general to improve the opera tion thereof.

Tn the accompanying drawing Fig. 1 shows a side elevation of one form ofdevice embodying my invention,

Fig. 2 shows a plan view of the same,

i Fig. 3 shows a side elevation partly in section of a modification ofthe device shown in Fig. 1,

Fig. ashows a side elevation of a still further modification,

Figs. 5 and 6 show end and side elevations respectively of the form offulcrumbarillustrated in Fig. 4,

Fig. 7 shows a sectional view taken on the line 7-7 of Fig. 6.

Referring in detailto the accompanying drawing, it will be seen that thedevice comprises a pinch bar 10 pivotally connected at one end 11 to alever 12. The lever has a sliding loop 13 which is pivotally conneotedto a fulcrum bar 14, the fulcrum bar having a foot 15 to engage theground.

' The loop 13 is made adjustable by means of a detent 16 and engagingteeth 17 formed on the under side of the lever. The detent is held inengagement with the teeth by means of a spring 18 lying between theupper portion of the loop and the lever.

As shown in Fig. 3 the fulcrum bar may be made extensible by forming itin two parts, 19 and 20 and connecting these parts together by a pall 21and ratchet teeth 22. Also as shown in Figs. 4. 5 and 6 two differentlengths of fulcrum bars 23 and 24 may be employed, both pivotallyconnected to the loop 13, and the longer one being adapted to swingupwardly beneath the lever Specification of Letters Patent.

12 and be held in this position by a bail When it is desired to employthe longer fulcrum bar in the place of the shorter one the fulcrum isallowed to swing downwardly into parallel relation with the shorterbar,-

as shown in Figs. 5 and 6. In this position a rib 26 on the long fulcrumbar will fit between the channel 27 on the shorter bar, as shown in Fig.7. i

The frontend of the pinch bar 10 is preferably flattened and splayed, asshown at 28; It fits beneath the rail and engages the ground. Inoperation the fulcrum of the lever is fixed at the desired height andthe lever is moved to the position shown in Fig. 1;. A. downward thruston the outer end of the lever will cause the pinch bar to be lifted andsimultaneously thrust forward so as to exert a sidewisethrust on therail. Continued action on the rail is obtained by moving the apparatusforwardly or raising the fulcrum point by means of the sliding loop orextensible fulcrum bar.

It will be noted that the tool is inexpensive to construct and thatowing to its arrangement the power applied at the lever or handle isgreatly multiplied at the point where the pinch bar engages the rail.With a tool of this character the entire track may be shifted laterallywith a small amount of power and in a minimum of time. The combinedaction of the lever and pinch bar is such as to insure that the toolwill not move away from. the rail even in comparatively soft ground.

Various changes in the construction and arrangement of the several partsof the device may be employed without departing from the spirit of myinvention as disclosed in the appended claims.

In Fig. 1 the fulcrum bar is adjustably held in place on the lever byengagement of a rounded end. 29 in depressions 30 formed on the underside of the lever. To slide the fulcrum bar lengthwise of the lever saidfulcrum bar is turned to present a flat side 31.

A pawl 21 has an extension 21 adapted to engage a notch 22- near theupper end of the part 19 to retain the parts 19 and 20 in telescopicposition for convenience in packing or carrying the tool.

The present device is light and compact and therefore is readily put inposition for operation. and is convenient and easy to transport. It isquick acting in its operation and its use will insure proper alignmentof the rails of a track.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. In an aligning device for railway tracks a pinchbar to engage beneath the rail at one end, a lever pivoted directly tothe opposite end of the pinch bar and a swinging fulcrum support for thelever intermediate the ends of the latter, said parts being initally setso that when the lever is moved downwardly at its outer end the pinchbar is raised and simultaneously thrust forward.

2. In an aligning device for railway tracks a pinch bar, an operatinglever'pivotally connected thereto atone end and a fulcrum bar pivotallyconnected to the lever and resting upon the ground, said fulcrum barbeing free to move angularly whereby to, permit the pinch bar to moveforwardly as the same is raised by the lever.

3. In an aligning device for railway tracks, a pinch bar, an operatinglever pivotally connected thereto at one end, a fulcrum bar pivotallyconnected to the lever and resting upon the ground, and means foradjusting the position of the fulcrum bar on the lever.

4L. In an. aligning device for railway tracks a pinch bar, an operatinglever pivotally connected to one end thereof, a loop slidahle andadiustahly mounted on the handle and a fulcrum bar resting on the:

means for retaining the loop and, fulcrum bar in adjusted position onthe handle, said means inclin'ling a series of depressions on the underside of the lever with which the rounded end of the fulcrum bar engages,

said fulcrum bar having a Hat side which is presented to the depressionswhen the said bar is swung upwardly.
